Here is how it works.... We go through the alphabet, and each add just ONE (Non-repeating) metaphysical word and its definition.
Once we reach Z, we can start over again with A, but.... no repeats. It keeps going, until we run out of words.

I will start with Letter A

Aura - The energy surrounding a person or the soul's 'life force'. It's vibration shows up in colors around a person, which reveals it's condition. It is omni present and has several layers. The normal layer to view is the physical first layer, but with practice, all layers can be viewed.

(sorry, not my turn I guess, but couldn't resist this - another of my favourites

Ecstasy - literally, to stand outside of oneself; Mircea Eliade described Shamanism as a 'technique of ecstasy', where the spirit ascends the World Tree and soars in at-one-ment with the Great Spirit. Sums it all up really !

Kundalini (ku??alin? ?????????) Sanskrit, literally "coiled". In Indian yoga, a "corporeal energy"[1] - an unconscious, instinctive or libidinal force or Shakti, envisioned either as a goddess or else as a sleeping serpent coiled at the base of the spine,[2][3][4] hence a number of English renderings of the term such as 'serpent power'. Kundalini is considered a part of the subtle body along with chakras (energy centres) and nadis (channels). The overall conception has many points in common with Chinese theories of acupuncture.

Yoga and Tantra propose that this energy may be "awoken" by such means as austerities, breath and other physical exercises, visualisation and chanting. It may then rise up a subtle channel at the spine (called Shushumna) to the head, bringing psychological illumination. Each chakra is said to contain special characteristics.[5] Yogis tend to attempt this alone, Tantrics in couples, both usually under the instruction of a guru.

When Kundalini Shakti is conceived as a goddess then, when it rises to the head it unites itself with the Supreme Being (Lord Shiva). The aspirant gets engrossed in deep meditation and infinite bliss.[6][7]

Loki or Loke is a god or giant in Norse mythology. The 13th century Icelandic Poetic Edda and Prose Edda, two of the very few sources of information regarding the figure, inconsistently place him among the Æsir, as his blood-brotherhood makes him a member of Odin's family. Although frequently mentioned in 13th century Icelandic sources, it is generally believed by scholars that it is unlikely that Loki was ever worshipped.[1]

In the Eddas, Loki is described as a son of Fárbauti and in the Prose Edda as also a son of Laufey.[2] Loki also had two brothers (Helbindi & Byleist) of whom nothing is known. Loki is introduced in the Prose Edda as the "contriver of all fraud". Tales regarding Loki in these sources often feature Loki mixing freely with the gods for a long time, even becoming Odin's blood brother before arranging the accidental murder of Baldr by Höðr in the Prose Edda book Gylfaginning. After Baldr's death, the Æsir restrain Loki with the entrails of his son Narfi. He is eventually freed and fights alongside the Jotun against the forces of the Æsir at Ragnarök.

Loki is not to be confused with the similarly named Útgarða-Loki, a king of the giants in Jötunheimr.

Phenomenology - "the study of structures of consciousness as experienced from the first-person point of view. The central structure of an experience is its intentionality, its being directed toward something, as it is an experience of or about some object. An experience is directed toward an object by virtue of its content or meaning (which represents the object) together with appropriate enabling conditions" (Stanford 2003).
